swingarm help

[onethumb]

Hi all, only me again,

I've just cleaned my rear swingarm ready for powder coating and I know one of the bushes needs replacing so was going to do both but I've just seen that I'm missing the pivot thrust bush (don't remember removing it) and one of the rear fork felt rings is in a bad way, can anyone tell me where I can get these parts and any tips on removing the old ones.


thanks, Steve

Replace both bushes and felts along with the pivot pin that wears more than the bushes, all Parts were available from Dave Silver but the pin is expensive. To get the bushes out use a padsaw or just a hacksaw blade to cut down the length and collape them inwards

Cheers bryanj, the pin looks in good nick, am I wrong to try it in the new bushes?
Also have you a link for the felt and the pivot thrust bushes, can't see them anywhere?

Thanks.

This is a top site. I'm loving the help.

Should be able to find them from the part number. Which model CB750 have you got?

I've just replaced the swing arm bushes and pivot pin on the CB750. I did try new bushes without renewing the pin at first, however it was a complete waste of time and effort. After fitting the new pin, all is as it should be again.

bush 52108-300-300
thrust 52109-283-300
felt 52145-283-000
pivot 52141-300-300
cap 52144-283-010

Now that's top service. Nice one Bryan.

Well if it has the thrusts it has to be the same as the 500 and I have oodles of books for those!!!

I second that.
Sorry should of said, I've got a 1978 cb750 f2.
Thanks for the heads up flatfour too many of the good people on here have said change the pin so stuff the budget and do it right.

[Bryanj]

If its an F2 it should not have seperate thrusts and all those numbers are wrong -- sorry

Thanks Dennis. No hiding place now.

I think you will find the collar unobtainable but i believe the earlier one has the same dimensions just different grease grooves

You also have the option of a needle roller upgrade from Wemoto.  http://www.wemoto.com/bikes/honda/cb_750_f2_sohc/78/picture/swinging_arm_pivot_bearing_kit/
